STRAINER FOR WASH OR OTHER BASINS.

SPECIFICATION forming part of Letters Patent N 0. 782,860, datedFebruary 21, 1905.

Application filed March 18, 1904. Serial No. 198,779

F (ti/Z whom it mag concern.-

' and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to characters of reference markedthereon, which form a partof this specification.

This invention has reference to improvements in strainers forwashbasins, washtrays, sinks, bath-tubs, urinal-basins, and the like;and the invention has for its principal object to provide a simple,neat, and cheap strainer adapted to be detachably arranged in the outletor spud of such basins, trays, tubs,

and the like with a view of providing a sanitary means for readilykeeping foreign matter from collecting upon the usual cross rods or barsarranged in the outlet pipe or spud and preventing large objects frompassing into and collecting in the waste-pipe and form an objectionableobstruction.

A further object of this invention is to provide a strainer of thecharacter hereinafter stated and one which is removably placed in theoutlet pipe or spud to enable its being often cleansed and when arrangedin its detachable relation in the outlet or spud still not interferingwith the use of the usual stopper which is employed with the basin, tub,or the like.

Other objects of this invention not at this time especially mentionedwill be fully understood from the following detailed description of myinvention.

My invention consists primarily in the novel strainer for waste-pipes orspuds of washbasins, wash-tra'ys, sinks, bath-tubs, urinalbasins, andthe like hereinafter more particularly set forth; and, furthermore, thisinvention consistscin the various arrangements and combinations ofparts, as well as in the details of the construction thereof, all ofwhich will be hereinafter more fully described and then position in thesaid outlet.

finally embodied in the clauses of the claim which are appended to andform an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, inwhich "Figure 1 is a sectional representation of a portion of awashbasin and its outlet or spud with the removable or detachablestrainer in Fig. 2 is a plan view of the said parts represented in saidFig. 1 with the stopper removed; and Fig. 3 is a similar view with thestrainer removed, illustrating the general arrangement and constructionof the parts of the usual form of outlet or spud for basins. Fig. 4 is aperspective view of the strainer. Fig. 5 is a sectional representationof an outlet orspud for basins provided with aremovable strainer of aslightlymodified construction, and Fig. 6 represents in plan a blank ofsheet metal from which the strainer indicated in said Fig. 5 is made.

Similar characters of reference are employed in the above-describedviews to indicate corresponding parts.

Referring now to the said'drawings, the reference character 1 indicatesa portion of a Washbasin provided with the usual outlet 2, in which issecured and arranged, by means of a nut 3 and a flanged part 4, theusual form of outlet pipe or spud 5, which is connected, by means of aunion 6, to the waste-pipe 7.- WVithin this outlet pipe or spud 5 arearranged in any suitable'manner, usually by being soldered in place, theusual cross-bars 8, as clearly illustrated in Fig. 3 of the drawings. Aswill be noticed from an inspection of the said Fig. 3, the arrangementof these bars 8 is such that very large open spaces 9 are formed. whichprovides no protection against large objectssuch as matches, hair-pins,and often buttons from entering the outlet-pipe 5 or of hair and otherforeign matter collecting upon the said cross-bars 8, and therebyproviding an unsanitary and unsightly condition of the outlet, which attimes is diflicult to clean and sometimes requires the plumber to removesuch obstruction and unclean condition of the pipe at the outlet ofthebasin. That this unclean and non-sanitary condition may be readilyovercome I have provided the outlet IOC or spud of the basin, tray, ortub with a removable strainer, as 10, which is easily forced into andheld preferably by frictional contact with the interior cylindricalsurface of the outlet pipe or spud 5, as will be presently described,and which can be easily .removed from day to day, if necessary, so as tobe cleaned by the most unskilled person by the simple insertion of theprong of a hair-pin or the blade of a knife into one of the perforations of the strainer to lift it from its position within the saidpipe or spud.

In practice I prefer to make this strainer '10 of any suitable sheetmetal, as brass or the like, the same comprising a disk-shaped body 11of approximately the diameter of the internal diameter of the said pipeor spud 5, the body 11 being provided with any suitable arrangement ofholes or perforations 12, some of which may be of a long and narrowconfiguration, as shown in the drawings; but this is not an absolutenecessity, and the plate or body 11 may be provided with any desiredarrangement of holes or perforations. Suitably secured against the undersurface of the said body or plate 12, by means of solder or any otherfastening means, is an arrangement of spring-arms lat, which areprovided with curved portions 15, adapted when the said strainer isinserted in position in the outlet pipe or stud 5 to be passed throughthe open spaces 9 with the curved portions 15 of the spring-arms 1%arranged in slidable holding engagement with the inner surface portionsof the pipe or spud 5, as clearly illustrated in Fig. 1 of the drawings.

Thus it will be seen that the strainer is easily removed from within theoutlet pipe or spud 5 and may be quickly replaced in its operativeposition therein, and it is held at the proper depth in the said pipe orspud so that the strainer will not interfere with the use of thestopper, which can be placed in the mouth of the said outlet pipe orspud 5 in the usual and well-known manner.

In Figs. 5 and 6 I have represented a slightlymodified construction ofstrainer in which the body or plate and the spring-arms are all madefrom a single piece of sheet metal, the said spring-arms beingintegrally connected with the circular edge of the main body or plate.In these figures the said plate or body is indicated by the referencecharacter 16 and the spring-arms by the numerals 17. The said body orplate is formed with the holes or perforations 18, and the said arms arebent into shape represented in said Fig. 5, being provided with therounded parts 19, which serve as holding portions for detachablyarranging this form of strainer in the said outlet pipe or spud 5.

I am aware that some changes may be made in the arrangements andcombinations of the parts without departing from the scope of thisinvention. Hence I do not limit my invention to the exact arrangementsand combinations of the parts as herein described and as illustrated inthe accompanying drawings, nor do I confine myself to the exact detailsof the construction of the said parts.

Having thus described my invention, what I claim is '1. The combination,with the outlet pipe or spud of a wash or other basin provided withcross-bars having openings between them, of a removable strainerconsisting, essentially, of a main disk substantially of the samediameter as the inner diameter of said pipe or spud, said disk beingprovided with perforations, and outwardly-curved anddiametrically-opposed spring-arms connected with the said disk, saidspring arms being passed through the openings formed by the crossbars ofthe outlet pipe or spud, and having portions in slidable and frictionalholding engagement with the inner surface of said outlet pipe or spudbelow said cross-bars, for adjustably arranging the said strainer-diskwithin the said pipe or spud, either, directly upon said cross-bars orat other points above the said cross-bars, substantially as and for thepurposes set forth.

2. The combination, with the outlet pipe or spud of a wash or otherbasin provided with cross-bars having openings between them, of aremovable strainer consisting, essentially, of a main disk substantiallyof the same diameter as the inner diameter of said pipe or spud, saiddisk being provided with perforations, a centrally-arrangedfastening-pin extending downwardly from the said disk, anddiametrically-opposed and downwardlyextending spring-arms secured bymeans of said pin at the center of the lower surface of said disk, saidarms being passed through the openings formed by the cross-bars of theoutlet pipe or spud, and curving outwardly and having their curvedportions in slidable and frictional holding engagement with the innersurface of said outlet pipe or spud below said cross-bars, foradjustably arranging the said strainer-disk within the said pipe orspud, either, directly upon said cross-bars or at other points above thesaid cross-bars, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 15th day of March, 190 i.

JOHN LEVER.
